Synergistic 3D π–π networks enforce persistent foldamer configuration with tunable full-color circularly polarized luminescence

Communications Chemistry
Achieving molecular chirality with enantiostability in purely π-conjugated foldamers remains a substantial challenge due to inherently weak π-π stacking interactions and facile racemization.
